ularly to narrow ware looms employing two or more banks of shuttles.In'looms of this type it becomes necessary to raise and lower the banksof shuttles so that as desired any one of the banks of shuttleswillbeinoperative position] This raising and lower.-

ing of the banks of shuttles is accomplished through the medium of achange-motion mechanism thatis directly controlled by an indicator.mechanism.. Aloom of the type referred 'to having af'ohangej-motionmechanisin and an indicator mechanisin for controllingthe operation ofthe 'change motion mechanism is shown-and describedin Patents Nos.786,237 dated March 28 1905 and 803,511' datedOctober .31, 1905, whichwere granted to me respectivelyflonthose dates. According to thepresent'invent1o1ithe in:

dicator mechanism is constructed so. that the members of thechange-motion mechanism back again. Thechange-motion mechanism memberswill be? positively held in each e2;- treme position by a camwhich'isconstructed to effect the positive movement/above referred to.

' The invention relates to the features above V referred to and also" toother features which willlbe hereinafterpointed out in the severalclaims constituting a partoffthis specifica- 'tion. i

. As .illustratinga specific embodiment of the invention reference ismade to the drawngforming a partof;

this specification, and in which drawing 7- Y i Figure 1 is a sideelevation showing the change-motion mechanism and the indicatormechanism for effecting a positive movement of the'change' gear ofthechange-motion mechanism from one extreme otherand back again. I t

In said drawing the change-motion mechplane indicated anism isdesignated by '1 and "the indicatormechanism by 2.; Said change-motionmechanism has a central crank-gear 3 which,

as will hereinaftera-ppear, maybe properly referred'to as thechange-gear. Around this 'crank-gear'there is arranged a semi-circularseries of meshing gears 45, 5,6 and 'zl The crank-gear 3 isarranged sothat it can be moved' 'or swung laterally? into engagement" w th oneorth'e other. of the end-gears 4,01" 7 of. the seml-c rcular serles, asdesiredf These end-gears as'well as the fcrank-gear 3 are properlymutilated in their engaging parts, as is usualin' this typeofconstruction soas t i u th Pr r m shi f r he re qu red; semi-rotation ofsaid i crank-gear I V opposite direotions'by the respective end:
